FIELD OF THE INVENTION

The present invention relates to the field of plant breeding and, morespecifically, to the development of tomato hybrid PS02326502 and theinbred tomato lines PSQ23-2233 and PSQ23-2258.

BACKGROUND OF THE INVENTION

The goal of vegetable breeding is to combine various desirable traits ina single variety/hybrid. Such desirable traits may include any traitdeemed beneficial by a grower and/or consumer, including greater yield,resistance to insects or disease, tolerance to environmental stress, andnutritional value.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same plant or plant variety. A plant cross-pollinates if pollencomes to it from a flower of a different plant variety.

Plants that have been self-pollinated and selected for type over manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny, a homozygous plant. A crossbetween two such homozygous plants of different genotypes produces auniform population of hybrid plants that are heterozygous for many geneloci. Conversely, a cross of two plants each heterozygous at a number ofloci produces a population of hybrid plants that differ genetically andare not uniform. The resulting non-uniformity makes performanceunpredictable.

The development of uniform varieties requires the development ofhomozygous inbred plants, the crossing of these inbred plants, and theevaluation of the crosses. Pedigree breeding and recurrent selection areexamples of breeding methods that have been used to develop inbredplants from breeding populations. Those breeding methods combine thegenetic backgrounds from two or more plants or various other broad-basedsources into breeding pools from which new lines and hybrids derivedtherefrom are developed by selfing and selection of desired phenotypes.The new lines and hybrids are evaluated to determine which of those havecommercial potential.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides a tomato plant of thehybrid designated PS02326502, the tomato line PSQ23-2233 or tomato linePSQ23-2258. Also provided are tomato plants having all the physiologicaland morphological characteristics of such a plant. Parts of these tomatoplants are also provided, for example, including pollen, an ovule,scion, a rootstock, a fruit, and a cell of the plant.

In another aspect of the invention, a plant of tomato hybrid PS02326502and/or tomato lines PSQ23-2233 and PSQ23-2258 comprising an addedheritable trait is provided. The heritable trait may comprise a geneticlocus that is, for example, a dominant or recessive allele. In oneembodiment of the invention, a plant of tomato hybrid PS02326502 and/ortomato lines PSQ23-2233 and PSQ23-2258 is defined as comprising a singlelocus conversion. In specific embodiments of the invention, an addedgenetic locus confers one or more traits such as, for example, herbicidetolerance, insect resistance, disease resistance, and modifiedcarbohydrate metabolism. In further embodiments, the trait may beconferred by a naturally occurring gene introduced into the genome of aline by backcrossing, a natural or induced mutation, or a transgeneintroduced through genetic transformation techniques into the plant or aprogenitor of any previous generation thereof. When introduced throughtransformation, a genetic locus may comprise one or more genesintegrated at a single chromosomal location.

The invention also concerns the seed of tomato hybrid PS02326502 and/ortomato lines PSQ23-2233 and PSQ23-2258. The tomato seed of the inventionmay be provided, in one embodiment of the invention, as an essentiallyhomogeneous population of tomato seed of tomato hybrid PS02326502 and/ortomato lines PSQ23-2233 and PSQ23-2258. Essentially homogeneouspopulations of seed are generally free from substantial numbers of otherseed. Therefore, seed of hybrid PS02326502 and/or tomato linesPSQ23-2233 and PSQ23-2258 may be defined, in specific embodiments, asforming at least about 97% of the total seed, including at least about98%, 99% or more of the seed. The seed population may be separatelygrown to provide an essentially homogeneous population of tomato plantsdesignated PS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258.

In yet another aspect of the invention, a tissue culture of regenerablecells of a tomato plant of hybrid PS02326502 and/or tomato linesPSQ23-2233 and PSQ23-2258 is provided. The tissue culture willpreferably be capable of regenerating tomato plants capable ofexpressing all of the physiological and morphological characteristics ofthe starting plant, and of regenerating plants having substantially thesame genotype as the starting plant. Examples of some of thephysiological and morphological characteristics of the hybrid PS02326502and/or tomato lines PSQ23-2233 and PSQ23-2258 include those traits setforth in the tables herein. The regenerable cells in such tissuecultures may be derived, for example, from embryos, meristems,cotyledons, pollen, leaves, anthers, roots, root tips, pistils, flowers,seed and stalks. Still further, the present invention provides tomatoplants regenerated from a tissue culture of the invention, the plantshaving all the physiological and morphological characteristics of hybridPS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258.

In still yet another aspect of the invention, processes are provided forproducing tomato seeds, plants and fruit, which processes generallycomprise crossing a first parent tomato plant with a second parenttomato plant, wherein at least one of the first or second parent tomatoplants is a plant of tomato line PSQ23-2233 or tomato line PSQ23-2258.These processes may be further exemplified as processes for preparinghybrid tomato seed or plants, wherein a first tomato plant is crossedwith a second tomato plant of a different, distinct genotype to providea hybrid that has, as one of its parents, a plant of tomato linePSQ23-2233 or tomato line PSQ23-2258. In these processes, crossing willresult in the production of seed. The seed production occurs regardlessof whether the seed is collected or not.

In one embodiment of the invention, the first step in “crossing”comprises planting seeds of a first and second parent tomato plant,often in proximity so that pollination will occur for example, mediatedby insect vectors. Alternatively, pollen can be transferred manually.Where the plant is self-pollinated, pollination may occur without theneed for direct human intervention other than plant cultivation.

A second step may comprise cultivating or growing the seeds of first andsecond parent tomato plants into plants that bear flowers. A third stepmay comprise preventing self-pollination of the plants, such as byemasculating the flowers (i.e., killing or removing the pollen).

A fourth step for a hybrid cross may comprise cross-pollination betweenthe first and second parent tomato plants. Yet another step comprisesharvesting the seeds from at least one of the parent tomato plants. Theharvested seed can be grown to produce a tomato plant or hybrid tomatoplant.

The present invention also provides the tomato seeds and plants producedby a process that comprises crossing a first parent tomato plant with asecond parent tomato plant, wherein at least one of the first or secondparent tomato plants is a plant of tomato hybrid PS02326502 and/ortomato lines PSQ23-2233 and PSQ23-2258. In one embodiment of theinvention, tomato seed and plants produced by the process are firstgeneration (F₁) hybrid tomato seed and plants produced by crossing aplant in accordance with the invention with another, distinct plant. Thepresent invention further contemplates plant parts of such an F₁ hybridtomato plant, and methods of use thereof. Therefore, certain exemplaryembodiments of the invention provide an F₁ hybrid tomato plant and seedthereof.

In still yet another aspect, the present invention provides a method ofproducing a plant derived from hybrid PS02326502 and/or tomato linesPSQ23-2233 and PSQ23-2258, the method comprising the steps of: (a)preparing a progeny plant derived from hybrid PS02326502 and/or tomatolines PSQ23-2233 and PSQ23-2258, wherein said preparing comprisescrossing a plant of the hybrid PS02326502 and/or tomato lines PSQ23-2233and PSQ23-2258 with a second plant; and (b) crossing the progeny plantwith itself or a second plant to produce a seed of a progeny plant of asubsequent generation. In further embodiments, the method mayadditionally comprise: (c) growing a progeny plant of a subsequentgeneration from said seed of a progeny plant of a subsequent generationand crossing the progeny plant of a subsequent generation with itself ora second plant; and repeating the steps for an additional 3-10generations to produce a plant derived from hybrid PS02326502 and/ortomato lines PSQ23-2233 and PSQ23-2258. The plant derived from hybridPS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258 may be aninbred line, and the aforementioned repeated crossing steps may bedefined as comprising sufficient inbreeding to produce the inbred line.In the method, it may be desirable to select particular plants resultingfrom step (c) for continued crossing according to steps (b) and (c). Byselecting plants having one or more desirable traits, a plant derivedfrom hybrid PS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258 isobtained which possesses some of the desirable traits of the line/hybridas well as potentially other selected traits.

In certain embodiments, the present invention provides a method ofproducing food or feed comprising: (a) obtaining a plant of tomatohybrid PS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258, whereinthe plant has been cultivated to maturity, and (b) collecting at leastone tomato from the plant.

In still yet another aspect of the invention, the genetic complement oftomato hybrid PS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258is provided. The phrase “genetic complement” is used to refer to theaggregate of nucleotide sequences, the expression of which sequencesdefines the phenotype of, in the present case, a tomato plant, or a cellor tissue of that plant. A genetic complement thus represents thegenetic makeup of a cell, tissue or plant, and a hybrid geneticcomplement represents the genetic make up of a hybrid cell, tissue orplant. The invention thus provides tomato plant cells that have agenetic complement in accordance with the tomato plant cells disclosedherein, and seeds and plants containing such cells.

Plant genetic complements may be assessed by genetic marker profiles,and by the expression of phenotypic traits that are characteristic ofthe expression of the genetic complement, e.g., isozyme typing profiles.It is understood that hybrid PS02326502 and/or tomato lines PSQ23-2233and PSQ23-2258 could be identified by any of the many well knowntechniques such as, for example, Simple Sequence Length Polymorphisms(SSLPs) (Williams et al., 1990), Randomly Amplified Polymorphic DNAs(RAPDs), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction(AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858,specifically incorporated herein by reference in its entirety), andSingle Nucleotide Polymorphisms (SNPs) (Wang et al., 1998).

In still yet another aspect, the present invention provides hybridgenetic complements, as represented by tomato plant cells, tissues,plants, and seeds, formed by the combination of a haploid geneticcomplement of a tomato plant of the invention with a haploid geneticcomplement of a second tomato plant, preferably, another, distincttomato plant. In another aspect, the present invention provides a tomatoplant regenerated from a tissue culture that comprises a hybrid geneticcomplement of this invention.

In still yet another aspect, the invention provides a plant of an hybridtomato that exhibits a combination of traits comprising a goodprocessing tomato; a determinate growth habit; a concentrated set ofsquare-round shaped fruit; good yield of fruit; a plant that is suitablefor mechanical harvest; jointless stems; a life history that is selectedmainly for growth in Southern Europe, especially Turkey, Italy andSpain; a high quality fruit with good color, brix and crackingtolerance; and resistance to Verticillium wilt race 0, Fusarium races 0and 1, Pseudomonas syringae pv. tomato race 0 and to tomato spotted wiltvirus. In certain embodiments, the combination of traits may be definedas controlled by genetic means for the expression of the combination oftraits found in tomato hybrid PS02326502.

In still yet another aspect, the invention provides a method ofdetermining the genotype of a plant of tomato hybrid PS02326502 and/ortomato lines PSQ23-2233 and PSQ23-2258 comprising detecting in thegenome of the plant at least a first polymorphism. The method may, incertain embodiments, comprise detecting a plurality of polymorphisms inthe genome of the plant. The method may further comprise storing theresults of the step of detecting the plurality of polymorphisms on acomputer readable medium. The invention further provides a computerreadable medium produced by such a method.

Any embodiment discussed herein with respect to one aspect of theinvention applies to other aspects of the invention as well, unlessspecifically noted.

C. Breeding Tomato Plants

One aspect of the current invention concerns methods for producing seedof tomato hybrid PS02326502 involving crossing tomato lines PSQ23-2233and PSQ23-2258. Alternatively, in other embodiments of the invention,hybrid PS02326502, line PSQ23-2233, or line PSQ23-2258 may be crossedwith itself or with any second plant. Such methods can be used forpropagation of hybrid PS02326502 and/or the tomato lines PSQ23-2233 andPSQ23-2258, or can be used to produce plants that are derived fromhybrid PS02326502 and/or the tomato lines PSQ23-2233 and PSQ23-2258.Plants derived from hybrid PS02326502 and/or the tomato lines PSQ23-2233and PSQ23-2258 may be used, in certain embodiments, for the developmentof new tomato varieties.

The development of new varieties using one or more starting varieties iswell known in the art. In accordance with the invention, novel varietiesmay be created by crossing hybrid PS02326502 followed by multiplegenerations of breeding according to such well known methods. Newvarieties may be created by crossing with any second plant. In selectingsuch a second plant to cross for the purpose of developing novel lines,it may be desired to choose those plants which either themselves exhibitone or more selected desirable characteristics or which exhibit thedesired characteristic(s) when in hybrid combination. Once initialcrosses have been made, inbreeding and selection take place to producenew varieties. For development of a uniform line, often five or moregenerations of selfing and selection are involved.

Uniform lines of new varieties may also be developed by way ofdouble-haploids. This technique allows the creation of true breedinglines without the need for multiple generations of selfing andselection. In this manner true breeding lines can be produced in aslittle as one generation. Haploid embryos may be produced frommicrospores, pollen, anther cultures, or ovary cultures. The haploidembryos may then be doubled autonomously, or by chemical treatments(e.g. colchicine treatment). Alternatively, haploid embryos may be growninto haploid plants and treated to induce chromosome doubling. In eithercase, fertile homozygous plants are obtained. In accordance with theinvention, any of such techniques may be used in connection with a plantof the invention and progeny thereof to achieve a homozygous line.

Backcrossing can also be used to improve an inbred plant. Backcrossingtransfers a specific desirable trait from one inbred or non-inbredsource to an inbred that lacks that trait. This can be accomplished, forexample, by first crossing a superior inbred (A) (recurrent parent) to adonor inbred (non-recurrent parent), which carries the appropriate locusor loci for the trait in question. The progeny of this cross are thenmated back to the superior recurrent parent (A) followed by selection inthe resultant progeny for the desired trait to be transferred from thenon-recurrent parent. After five or more backcross generations withselection for the desired trait, the progeny have the characteristicbeing transferred, but are like the superior parent for most or almostall other loci. The last backcross generation would be selfed to givepure breeding progeny for the trait being transferred.

The plants of the present invention are particularly well suited for thedevelopment of new lines based on the elite nature of the geneticbackground of the plants. In selecting a second plant to cross withPS02326502 and/or tomato lines PSQ23-2233 and PSQ23-2258 for the purposeof developing novel tomato lines, it will typically be preferred tochoose those plants which either themselves exhibit one or more selecteddesirable characteristics or which exhibit the desired characteristic(s)when in hybrid combination. Examples of desirable traits may include, inspecific embodiments, high seed yield, high seed germination, seedlingvigor, high fruit yield, disease tolerance or resistance, andadaptability for soil and climate conditions. Consumer-driven traits,such as a fruit shape, color, texture, and taste are other examples oftraits that may be incorporated into new lines of tomato plantsdeveloped by this invention.

E. Further Embodiments of the Invention

In certain aspects of the invention, plants described herein areprovided modified to include at least a first desired heritable trait.Such plants may, in one embodiment, be developed by a plant breedingtechnique called backcrossing, wherein essentially all of themorphological and physiological characteristics of a variety arerecovered in addition to a genetic locus transferred into the plant viathe backcrossing technique. The term single locus converted plant asused herein refers to those tomato plants which are developed by a plantbreeding technique called backcrossing, wherein essentially all of themorphological and physiological characteristics of a variety arerecovered in addition to the single locus transferred into the varietyvia the backcrossing technique. By essentially all of the morphologicaland physiological characteristics, it is meant that the characteristicsof a plant are recovered that are otherwise present when compared in thesame environment, other than an occasional variant trait that mightarise during backcrossing or direct introduction of a transgene.

Backcrossing methods can be used with the present invention to improveor introduce a characteristic into the present variety. The parentaltomato plant which contributes the locus for the desired characteristicis termed the nonrecurrent or donor parent. This terminology refers tothe fact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental tomato plant towhich the locus or loci from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol.

In a typical backcross protocol, the original variety of interest(recurrent parent) is crossed to a second variety (nonrecurrent parent)that carries the single locus of interest to be transferred. Theresulting progeny from this cross are then crossed again to therecurrent parent and the process is repeated until a tomato plant isobtained wherein essentially all of the morphological and physiologicalcharacteristics of the recurrent parent are recovered in the convertedplant, in addition to the single transferred locus from the nonrecurrentparent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single locus of the recurrent variety ismodified or substituted with the desired locus from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphologicalconstitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross; one ofthe major purposes is to add some commercially desirable trait to theplant. The exact backcrossing protocol will depend on the characteristicor trait being altered and the genetic distance between the recurrentand nonrecurrent parents. Although backcrossing methods are simplifiedwhen the characteristic being transferred is a dominant allele, arecessive allele, or an additive allele (between recessive anddominant), may also be transferred. In this instance it may be necessaryto introduce a test of the progeny to determine if the desiredcharacteristic has been successfully transferred.

In one embodiment, progeny tomato plants of a backcross in which a plantdescribed herein is the recurrent parent comprise (i) the desired traitfrom the non-recurrent parent and (ii) all of the physiological andmorphological characteristics of tomato the recurrent parent asdetermined at the 5% significance level when grown in the sameenvironmental conditions.

New varieties can also be developed from more than two parents. Thetechnique, known as modified backcrossing, uses different recurrentparents during the backcrossing. Modified backcrossing may be used toreplace the original recurrent parent with a variety having certain moredesirable characteristics or multiple parents may be used to obtaindifferent desirable characteristics from each.

Many single locus traits have been identified that are not regularlyselected for in the development of a new inbred but that can be improvedby backcrossing techniques. Single locus traits may or may not betransgenic; examples of these traits include, but are not limited to,herbicide resistance, resistance to bacterial, fungal, or viral disease,insect resistance, modified fatty acid or carbohydrate metabolism, andaltered nutritional quality. These comprise genes generally inheritedthrough the nucleus.

Direct selection may be applied where the single locus acts as adominant trait. For this selection process, the progeny of the initialcross are assayed for viral resistance and/or the presence of thecorresponding gene prior to the backcrossing. Selection eliminates anyplants that do not have the desired gene and resistance trait, and onlythose plants that have the trait are used in the subsequent backcross.This process is then repeated for all additional backcross generations.

Selection of tomato plants for breeding is not necessarily dependent onthe phenotype of a plant and instead can be based on geneticinvestigations. For example, one can utilize a suitable genetic markerwhich is closely genetically linked to a trait of interest. One of thesemarkers can be used to identify the presence or absence of a trait inthe offspring of a particular cross, and can be used in selection ofprogeny for continued breeding. This technique is commonly referred toas marker assisted selection. Any other type of genetic marker or otherassay which is able to identify the relative presence or absence of atrait of interest in a plant can also be useful for breeding purposes.Procedures for marker assisted selection are well known in the art. Suchmethods will be of particular utility in the case of recessive traitsand variable phenotypes, or where conventional assays may be moreexpensive, time consuming or otherwise disadvantageous. Types of geneticmarkers which could be used in accordance with the invention include,but are not necessarily limited to, Simple Sequence Length Polymorphisms(SSLPs) (Williams et al., 1990), Randomly Amplified Polymorphic DNAs(RAPDs), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction(AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858,specifically incorporated herein by reference in its entirety), andSingle Nucleotide Polymorphisms (SNPs) (Wang et al., 1998).

F. Plants Derived by Genetic Engineering

Many useful traits that can be introduced by backcrossing, as well asdirectly into a plant, are those which are introduced by genetictransformation techniques. Genetic transformation may therefore be usedto insert a selected transgene into a plant of the invention or may,alternatively, be used for the preparation of transgenes which can beintroduced by backcrossing. Methods for the transformation of plantsthat are well known to those of skill in the art and applicable to manycrop species include, but are not limited to, electroporation,microprojectile bombardment, Agrobacterium-mediated transformation anddirect DNA uptake by protoplasts.

To effect transformation by electroporation, one may employ eitherfriable tissues, such as a suspension culture of cells or embryogeniccallus or alternatively one may transform immature embryos or otherorganized tissue directly. In this technique, one would partiallydegrade the cell walls of the chosen cells by exposing them topectin-degrading enzymes (pectolyases) or mechanically wound tissues ina controlled manner.

An efficient method for delivering transforming DNA segments to plantcells is microprojectile bombardment. In this method, particles arecoated with nucleic acids and delivered into cells by a propellingforce. Exemplary particles include those comprised of tungsten,platinum, and preferably, gold. For the bombardment, cells in suspensionare concentrated on filters or solid culture medium. Alternatively,immature embryos or other target cells may be arranged on solid culturemedium. The cells to be bombarded are positioned at an appropriatedistance below the macroprojectile stopping plate.

An illustrative embodiment of a method for delivering DNA into plantcells by acceleration is the Biolistics Particle Delivery System, whichcan be used to propel particles coated with DNA or cells through ascreen, such as a stainless steel or Nytex screen, onto a surfacecovered with target cells. The screen disperses the particles so thatthey are not delivered to the recipient cells in large aggregates.Microprojectile bombardment techniques are widely applicable, and may beused to transform virtually any plant species.

Agrobacterium-mediated transfer is another widely applicable system forintroducing gene loci into plant cells. An advantage of the technique isthat DNA can be introduced into whole plant tissues, thereby bypassingthe need for regeneration of an intact plant from a protoplast. ModernAgrobacterium transformation vectors are capable of replication in E.coli as well as Agrobacterium, allowing for convenient manipulations(Klee et al., 1985). Moreover, recent technological advances in vectorsfor Agrobacterium-mediated gene transfer have improved the arrangementof genes and restriction sites in the vectors to facilitate theconstruction of vectors capable of expressing various polypeptide codinggenes. The vectors described have convenient multi-linker regionsflanked by a promoter and a polyadenylation site for direct expressionof inserted polypeptide coding genes. Additionally, Agrobacteriumcontaining both armed and disarmed Ti genes can be used fortransformation.

In those plant strains where Agrobacterium-mediated transformation isefficient, it is the method of choice because of the facile and definednature of the gene locus transfer. The use of Agrobacterium-mediatedplant integrating vectors to introduce DNA into plant cells is wellknown in the art (Fraley et al., 1985; U.S. Pat. No. 5,563,055).

Transformation of plant protoplasts also can be achieved using methodsbased on calcium phosphate precipitation, polyethylene glycol treatment,electroporation, and combinations of these treatments (see, e.g.,Potrykus et al., 1985; Omirulleh et al., 1993; Fromm et al., 1986;Uchimiya et al., 1986; Marcotte et al., 1988). Transformation of plantsand expression of foreign genetic elements is exemplified in Choi et al.(1994), and Ellul et al. (2003).

A number of promoters have utility for plant gene expression for anygene of interest including but not limited to selectable markers,scoreable markers, genes for pest tolerance, disease resistance,nutritional enhancements and any other gene of agronomic interest.Examples of constitutive promoters useful for plant gene expressioninclude, but are not limited to, the cauliflower mosaic virus (CaMV)P-35S promoter, which confers constitutive, high-level expression inmost plant tissues (see, e.g., Odel et al., 1985), including in monocots(see, e.g., Dekeyser et al., 1990; Terada and Shimamoto, 1990); atandemly duplicated version of the CaMV 35S promoter, the enhanced 35Spromoter (P-e35S); l the nopaline synthase promoter (An et al., 1988);the octopine synthase promoter (Fromm et al., 1989); and the figwortmosaic virus (P-FMV) promoter as described in U.S. Pat. No. 5,378,619and an enhanced version of the FMV promoter (P-eFMV) where the promotersequence of P-FMV is duplicated in tandem; the cauliflower mosaic virus19S promoter; a sugarcane bacilliform virus promoter; a commelina yellowmottle virus promoter; and other plant DNA virus promoters known toexpress in plant cells.

A variety of plant gene promoters that are regulated in response toenvironmental, hormonal, chemical, and/or developmental signals can alsobe used for expression of an operably linked gene in plant cells,including promoters regulated by (1) heat (Callis et al., 1988), (2)light (e.g., pea rbcS-3A promoter, Kuhlemeier et al., 1989; maize rbcSpromoter, Schaffner and Sheen, 1991; or chlorophyll a/b-binding proteinpromoter, Simpson et al., 1985), (3) hormones, such as abscisic acid(Marcotte et al., 1989), (4) wounding (e.g., wunl, Siebertz et al.,1989); or (5) chemicals such as methyl jasmonate, salicylic acid, orSafener. It may also be advantageous to employ organ-specific promoters(e.g., Roshal et al., 1987; Schernthaner et al., 1988; Bustos et al.,1989).

Exemplary nucleic acids which may be introduced to plants of thisinvention include, for example, DNA sequences or genes from anotherspecies, or even genes or sequences which originate with or are presentin the same species, but are incorporated into recipient cells bygenetic engineering methods rather than classical reproduction orbreeding techniques. However, the term “exogenous” is also intended torefer to genes that are not normally present in the cell beingtransformed, or perhaps simply not present in the form, structure, etc.,as found in the transforming DNA segment or gene, or genes which arenormally present and that one desires to express in a manner thatdiffers from the natural expression pattern, e.g., to over-express.Thus, the term “exogenous” gene or DNA is intended to refer to any geneor DNA segment that is introduced into a recipient cell, regardless ofwhether a similar gene may already be present in such a cell. The typeof DNA included in the exogenous DNA can include DNA which is alreadypresent in the plant cell, DNA from another plant, DNA from a differentorganism, or a DNA generated externally, such as a DNA sequencecontaining an antisense message of a gene, or a DNA sequence encoding asynthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and couldpotentially be introduced into a tomato plant according to theinvention. Non-limiting examples of particular genes and correspondingphenotypes one may choose to introduce into a tomato plant include oneor more genes for insect tolerance, such as a Bacillus thuringiensis(B.t.) gene, pest tolerance such as genes for fungal disease control,herbicide tolerance such as genes conferring glyphosate tolerance, andgenes for quality improvements such as yield, nutritional enhancements,environmental or stress tolerances, or any desirable changes in plantphysiology, growth, development, morphology or plant product(s). Forexample, structural genes would include any gene that confers insecttolerance including but not limited to a Bacillus insect control proteingene as described in WO 99/31248, herein incorporated by reference inits entirety, U.S. Pat. No. 5,689,052, herein incorporated by referencein its entirety, U.S. Pat. Nos. 5,500,365 and 5,880,275, hereinincorporated by reference in their entirety. In another embodiment, thestructural gene can confer tolerance to the herbicide glyphosate asconferred by genes including, but not limited to Agrobacterium strainCP4 glyphosate resistant EPSPS gene (aroA:CP4) as described in U.S. Pat.No. 5,633,435, herein incorporated by reference in its entirety, orglyphosate oxidoreductase gene (GOX) as described in U.S. Pat. No.5,463,175, herein incorporated by reference in its entirety.

Alternatively, the DNA coding sequences can affect these phenotypes byencoding a non-translatable RNA molecule that causes the targetedinhibition of expression of an endogenous gene, for example viaantisense- or cosuppression-mediated mechanisms (see, for example, Birdet al., 1991). The RNA could also be a catalytic RNA molecule (i.e., aribozyme) engineered to cleave a desired endogenous mRNA product (seefor example, Gibson and Shillito, 1997). Thus, any gene which produces aprotein or mRNA which expresses a phenotype or morphology change ofinterest is useful for the practice of the present invention.
